[Industrial applications]

 TECHNICAL FIELD The present invention relates to a building scaffolding eaves device for attaching a sunshade and a rainproof eaves sheet to the upper end of the building scaffolding.

[0002]

[Prior art]

 At the construction site, we assemble the building scaffolds along the structure of the building under construction, go in and out of the building skeleton for interior work, and perform exterior work on the building skeleton. Suspension is bad and dangerous. Conventionally, there is a technique described in Japanese Patent Application Laid-Open No. 6-146612 as a solution to the above problems. In this method, a plurality of eaves supporting rods are arranged parallel to each other on the upper end of a building scaffold at regular intervals in the horizontal direction, and eaves sheets are attached on the eaves supporting rods.

[0003]

[Problems to be solved by the device]

 In the above conventional structure, each eaves supporting rod is only connected to the upper end of the building frame that constitutes the uppermost stage of the building scaffolding, so the eaves supporting rod connected to the upper end is easily rocked to the left and right. It is structured. Therefore, when the eaves sheet receives wind, the eaves support rod swings to the left and right, the eaves sheet is pushed up and down, noise is generated, and the upper part of the building scaffold vibrates, which is dangerous. .

In view of the above-mentioned conventional drawbacks, the present invention provides an eaves device for a building scaffolding in which the eaves supporting rod supporting the eaves sheet does not swing left and right even when the eaves sheet receives wind. It is an object.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the invention according to claim 1 is such that the eaves supporting rods are attached to the front and rear upper ends of the building scaffold, and the eaves supporting rods attached to the front and rear upper ends of the building scaffold are parallel to each other in the horizontal direction. The eaves supporting rods are arranged at predetermined intervals, and the plurality of eaves supporting rods are integrally connected to each other via the cross braces provided between the eaves supporting rods adjacent to each other, and the eaves supporting rods are mounted on the eaves supporting rods. The feature is that the seat is attached.

According to a second aspect of the present invention, in the first aspect of the present invention, the plurality of eaves supporting rods are expandable and contractable to a supporting rod main body connected to a building scaffold and a tip opening portion of the supporting rod main body. It consists of a telescopic rod that is inserted and locked to the support rod main body at a predetermined insertion position.The cross braces are installed between the two support rod main bodies that are adjacent to each other. It is characterized in that a connecting rod is installed on at least one of the rear ends of the rod main body.

According to a third aspect of the invention, in the second aspect of the invention, the cross bar, the connecting rod and / or the eaves sheet are locked to the both ends of the support rod body and the tip end of the expandable rod, respectively. Locking tools are provided, and each locking tool is provided with a fitting pin projecting from both ends of the support rod body and the tip of the expansion and contraction bar, and horizontally supported at the upper end of the fitting pin. To prevent the cross braces, connecting rods, and / or eaves sheets that are fitted to the fitting pins from coming off the fitting pins, and, when vertical, cross braces, connecting rods, and / or eaves sheets. It is characterized in that it is composed of a stopper that allows the connector to be disengaged from the fitting pin.

[0008]

[Action]

 The invention according to claim 1, wherein eaves supporting rods are sequentially attached to the front and rear upper ends of the building scaffolds arranged in parallel at predetermined intervals in the horizontal direction, and subsequently, the eaves supporting rods adjacent to each other are crossed. The braces may be installed and the eaves sheet may be attached to each of the eaves supporting rods. This allows construction work to be performed without being significantly affected by rainfall and sunshine.

In this case, since the eaves supporting rods are attached to the front and rear upper ends of the building scaffolding and the eaves supporting rods are reinforced by the cross braces so as not to swing left and right, even if the eaves sheet receives wind. , The eaves seats are prevented from being pushed up and down, noise is generated, and the upper part of the building scaffolding is prevented from vibrating, so that the construction work can be safely performed. Also, since the crossing braces support the eaves sheet, a large sag of the eaves sheet is prevented.

According to the second aspect of the invention, the eaves seat can be attached in a tensioned state between the telescopic rod and the support rod body by appropriately adjusting the telescopic length of the telescopic rod. Moreover, the cross braces are installed between the two supporting rod main bodies adjacent to each other, and the connecting rods are installed between at least one of the tip ends of the expanding and contracting rods adjacent to each other and between the rear end parts of the supporting rod bodies. Further, since the end portions of the eaves sheet are attached to the connecting rod at predetermined intervals in the width direction, it is possible to reliably prevent the eaves sheet from being lifted up and down even when a strong wind is received.

According to the third aspect of the present invention, the stopper is vertical and the fitting pin is provided with a cross bar, and the connecting rod and / or the eaves sheet are simply fitted, and the cross bar, the connecting rod, and the connecting bar are connected. Alternatively, the eaves sheet can be easily locked to both ends of the support rod body and the tip of the expansion and contraction rod. In this locked state, the stopper is substantially horizontal and there are no cross streaks or connecting rods. And / or the eaves sheet can be prevented from coming off from the fitting pin, so that the locked state can be reliably held. From this locked and held state, the stopper is made vertical and the cross braces and the connecting rods are connected. And / or the pulling of the eaves sheet upward can easily cancel the locked state.

Can be drained to the side. Further, by appropriately sliding the sliding cylinder portion 7b, the distance L between the support pipe portions 6a and 7a can be matched with the distance between the indoor and outdoor vertical pipes 11 and 12 of the building frame 2a. Further, by appropriately adjusting the extension / contraction length of the extension rod 4b, the eaves sheet 5 can be attached between the extension rod 4b and the support rod body 4a in a tensioned state.

As shown in FIGS. 7 and 8, the locking tool 9 includes fitting pins 9a projecting from both ends of the support rod body 4a and the tip of the telescopic rod 4b, and the fitting pin 9a. As shown in FIG. 8, the stopper 9b is inserted into a recess 17 formed at the tip of the pin 9a and is pivotally supported by an elongated hole in the center through a pivot shaft 18 so as to be vertically swingable. , The stopper 9b is made vertical, and the fitting pin 9a is provided with the cross brace 2c and / or the through holes 14 at both ends of the connecting rod 8 and the holes 16 of the eyelets 15 fixed to the eaves sheet 5 at predetermined intervals.

Since the top 9b is substantially horizontal, it prevents the cross braces 2c, the connecting rod 8 and the eaves sheet 5 from coming off from the fitting pin 9a, so that the locked state is surely maintained. From this locked and held state, the stopper 9b can be made vertical, and the locked state can be easily eliminated by only pulling the cross pad 2c, the connecting rod 8 and / or the eaves sheet 5 upward. You can

The procedure of the construction work will be described based on the above configuration. After assembling the building scaffold 2 along the building frame 1, a plurality of eaves supporting rods 4 are arranged on the front and rear upper ends of the building scaffold 2 in parallel with each other. Are arranged at predetermined intervals in the horizontal direction, and subsequently, the cross braces 2c are erected between the support rod main bodies 4a of the eaves support rods 4 via the fasteners 9 and the ends of the telescopic rods 4b are engaged with each other. The connecting rod 8 may be installed via the stopper 9, and the eaves sheet 5 may be mounted on the eaves supporting rod 4 via the locking device 9.
